Abstract
Abstract
Aluminum alloy 7050 has been widely used in the structure of aerospace vehicles because of its excellent comprehensive performance. In this paper, based on the extended finite element method and classical theory, the material parameters in the finite element simulation are calculated, next the metal plate with a central pre-crack is analyzed for static load breaking and fatigue damage under cyclic loading, the observation of different loading levels and the damage characteristics under different preset crack lengths are summarized, the rules are summarized to provide support for follow-up work.
